Record Picker Shows Record ID#, not Reference Proxy in Grid Edit

When I go to edit a Proxy Reference field in Grid Edit, it only shows the Record ID, though I've changed the Record Picker options in the parent record's Advanced Settings. Two screen shots below: Parent Record advanced settings for Record Picker; and, Grid Edit view from the child record showing the oddity.

There are two things you can check:(1) are you using the proxy field in the grid edit report? and not the reference field.(2) Under the 'form' settings page you can set what behavior you use during grid edit.
